coin in jam and meter disconnected?

I don't have the schematics of the power supply readily available on-hand Busch
but it's also possible that there's just some dirty, oxidized pins too!  
I'm also not sure which model PS you have either.

Would you have some electronics contact spray cleaner around?
I'd spray some pins too!
It doesn't hurt to have clean pins in the Molex connectors!

about the PSs is true, I figure out a way to see the DC powers. The pins and all I cleaned thoroughly with contact cleaner etc, all pin and other contacts I could find. I think best way to go is replace all components which might be or contribute to the errors, I am busy checking around, any business affiliated here I give preference if possible.
Thanks again, I am not so worried about the problem per se, looks like is common, but the way it just appeared while machine was in play...

so long

Hi again,
looks like my problems with I games continue. Are these games generally unreliable? I have a couple of Game Makers, they hardly ever give me trouble, and if, I can resolve it normally. Never my I games or Game Kings work more than 2 or 3 months without trrouble.
 How are those newer Ballys, Alpha or 9000 in terms of reliability? any experrience there? I have 3 GameMagic, all 3 out of order after short time, nobody coud help.
Yesterday another one broke down: Cleopatra, while on idle, a very loud explosion inside, smoke and all, I found the 2nd battery on MPU burned totally! why no idea.
Cleaned and changed and checked, now on power up the monitor only displays those funny coloured squares...with other board is ok, so I need another board there also I guess.
Now: is there anybody who could sell to me those parts and ship to Africa ( I/O boards, MPUs, DC powersupplies) sound easy, but so far I found nobody. I checked the links given in this forum...
thank you for any info

I have a coin in jam on a igt gameking bar top, the game has a jumper and i changed out the i/o cards.any idea on what i can do to fix this problem

if you have machines dyeing on a regular bases something is probably wrong with your power line. if you are missing i/o boards in a previously working machine you have a thief their is no way for an igt s2000 or igame to work with out a door or cabinet i/o board. some machines maybe have multiple of each board depending on the displays and buttons it is configured with. if your game is supposed to have multiple of one type of board the error displayed may not be the correct fault, a lot the SENET devices are chained into each other and i have seen the mpu get confused.
